To all whom t may concern: i

Beit known that I, JAMES E. PALMEn, commander, UQS. Navy, retired, and a citizen of the United States, residing at present .at Atlantic City, in the county of Atlantic and State of New Jersey, have=invented certain new and useful Improvements in Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to ventilators, espef cially adapted for rooms having windows and radiators, and has for its objectl to pro vide an apparatus 0f this kind which will be inexpensive to construct, and more eiicient in action than those heretofore proposed.

With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed Aand particularly pointed out in theiclaims. t I

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like partsin all the views:

Figurel is a diagrammatic plan view of a ventilator made in accordance with this invention; and

Fig. 2 is a sectional view on the line 2-2 of Fig. 1,'1ooking in the direction of the arrows'.

1 indicates a window or other opening for fresh air, 2 the sash or frame, 3 the opening through which air enters the room 4, 5 a

. window sill or other portion of the walls of room 4, 6 any suitable frame or conduit for conveying air from opening 3 into said roomv wall 8 and a radiator or other source of heat 9, and 10 a shield, `casin or deector adapted to partially surroun the radiator 9, and prevent the cold air from creating a draft along the floor 11.

'12 indicates a loose board, a piece of felt, or other suitable means adaptedto overlie the top 13 of the conduit 6, and to bridge the space 14 between said top and the win dow pane 15, and thus prevent the cold air from escaping through said space 14:.'

. Said felt 12 conveniently its against the pane 15 while not preventing the ready opening and vclosing ofthe window 1.

It will thus be seen that in operation, my

invention receivescold air through opening 3, d elivers it into the room at the top of and behind the radiator 9, and forces it to descend down A into the space A17 between the said radiator and wall, where it is more or less heated up and whence it being heavier than the warm air of the room, it finds its way into the well or pocket 18 formed by the defiector or casing '10, fitting the floor and com elling said air to ascend, all as is indicate by the arrows.

The pressure of the oncoming air, as well as the heat imparted .to it from the radiator will cause said cold air to diffuse itself from the space 17 and from the pocket 18 out into the rooin'without producing the objectionable drafts that are found to accompany the use of certain other ventilators of well known types.

attached to and detached from the window sill 5. In fact it`may be fashioned to it said sill, and permanently fastened thereto, or it may be merely loosely placed in position 75 The entire frame or conduit 6 is readily as the arrangement of parts without departingV from the spirit of the invention, and

therefore, I do not wish to be limited to the above disclosure except as may be required by the claims. What I claim is:- 1. In a ventilator for a room, the combination of a vertically disposed source lof heat; means to provide a space for cold air kin close proximit to said source of heat; a

readily removab e conduit provided with means for delivering cold air near the top 'of said source of heat and into said space; and means associated with said space andsource of heat constituting, a well to receive said air and adapted to prevent said cold air from forming-drafts along the oor'of the room, substantially as' described. 2. In a ventilator, for a room, the combination of a source of heat; means comprising a conining-wall surface to provide a Vspace for Acold air in close proximity to said source of heat; a readily removable conduit ioo adapted to t a window sill provided with means for delivering cold air at' the top of said source of'heat and into said space; and means comprising a casing fitting the floor associated with said space and source `of heat adapted to prevent said cold air'fromv said radiator when said window is open;-

forming drafts along the floor of the room, substantially as described..

3. In a'window ventilator for a roomfprovided with aradiator the combination of a conduit adapted to fit the window sill, and having an exit means adapted to deliver cold air into'said room-at the top of and behind means fitting the ioor to constitute a well to receive said cold air and a flexible member extending from said conduit vto saidvwindow bination of a radiator spaced from a wall of said room; a Window opening into said room; a readily movable lconduit fitting the window sill provided with an exit located at the top of said radiator and adapted to deliver cold'air from said window into the space between said radiator and wall; flexible means to prevent the leakage of air beltween said window and conduit; and means fitting the floor to form a well, and partially encircling said radiator to prevent drafts on the floor of said room, substantially as described.

In testimony whereof I aiix my si JAMES E. PAL ER.
